Red Hat recommended SWAP to be no larger than 4Gb,
1) Show current swap
swapon -s
2) Unmount Swap
swapoff /dev/mapper/VolGroup00-LogVol01
3) Reduce from 54Gb to 4Gb (Each LV Extent is 32Mb)
lvreduce -l -1600 /dev/VolGroup00/LogVol01
4) Reformat swap
mkswap /dev/VolGroup00/LogVol01
5) Mount swap as defined in /etc/fstab
swapon -a
